SCO-spondin is specifically expressed in the subcommissural organ (SCO), a secretory ependymal differentiation lining the roof of the third ventricular cavity of the brain. When released into the cerebro-spinal fluid (CSF), SCO-spondin aggregates and forms Reissner's fiber (RF), a structure present in the central canal of the spinal cord. SCO-spondin belongs to the superfamily of proteins exhibiting conserved motifs called TSRs for 'thrombospondin type 1 repeats' and involved in axonal pathfinding during development. The mouse SCO-spondin coding sequence was searched by alignement of the coding bovine SCO-spondin sequence with the mouse whole genome shotgun (WGS) supercontig (NW 000250). Compared to the bovine, mouse SCO-spondin shows 66.8% identity of amino acids. This extracellular matrix glycoprotein has a modular arrangement of several conserved domains including 25 TSRs, 10 low-density lipoprotein receptor (LDLr) type A repeats and cystein-rich regions in the -NH2 and -COOH ends. The spatio-temporal expression of SCO-spondin was analyzed using specific antisera and an homospecific SCO-spondin riboprobe. In the adult, the patterns obtained by in situ hybridization (ISH) and immunohistochemistry correlated well in the SCO, while Reissner's fiber and the ampulla caudalis were immunoreactive only. In the fetus, both the immuno and ISH reactions appeared between 14 and 15 days post coïtum (dpc) in the SCO anlage. In addition, the mouse SCO-spondin gene was located at chromosome 6, between marker D6Mit352 and D6Mit119, in a conserved syntenic region.
